Running back Marcus Lattimore, who was cleared to resume full practice in the offseason, was one of six players declared on the non-football injury list to open training camp.

The 49ers’ rookies reported to training camp on Wednesday. The non-football injury and physically-unable-to-perform lists are procedural lists from which a player can be removed at any time to begin practice.

Lattimore was allowed to report with the rookies because he does not have an accrued year of NFL service after spending his rookie season on the NFI list due to a knee injury he sustained during his final season at South Carolina.
